nothing major. if you watched the raw but dont know japanese there's probably only one thing you wouldnt be able to tell. spoiler tagged anyways.first character interaction between misaki and yuuno, iirc.
some more ginko. she says she started her info gathering profession for him, gets jealous of yuuno, etc.
misaki gets depressed because she starts thinking that she's just a job to shinkurou(and one he wanted to turn down but couldnt because of benika). shinkurou doesnt really notice.
they get in a fight because murasaki stands up for some old woman getting picked on and shinkurou does the stereotypical japanese thing and doesnt want to fight, but apologizes and ends up having to take a bit of punishment in murasaki's stead. but you should be able to tell that just from watching.
it's mostly just developing murasaki more.
